Length of the female, |ths of an inch; length of the cephalo-thorax, jth ; breadth, ith ; 
breadth of the abdomen, 55 ths ; length of a posterior leg, §; length of a leg of the third 
pair, ^ths. 
The intermediate eyes of the anterior row are rather larger than the lateral ones. The 
cephalo-thorax is of a red-brown colour, with a broad, irregular, brownish-black band on each 
side, narrow lateral margins of the same hue, and is clothed with yellowish-white hairs. The 
falces are powerful, conical, armed with teeth on the inner surface, and of a dark, reddish- 
brown colour, being palest in front. The maxillae are slightly curved towards the lip, and, 
with the latter, are of a dark-brown colour, tinged with red at the extremity. The sternum is 
heart-shaped, and has a brownish-black hue. The legs and palpi are robust, provided with 
hairs and spines, and are of a pale, reddish-brown colour with brownish-black annuli. The 
abdomen is oviform, hairy, rather broader at the posterior than at the anterior extremity, 
convex above, projecting over the base of the cephalo-thorax; its prevailing colour is dull or 
brownish-yellow, the under part being yellowish-white; in front of the upper part, contiguous 
to the cephalo-thorax, there is a large, tripartite, brownish-black mark, the intermediate 
division, which is the smallest, being bifid; to this succeeds a yellowish-white mark of a 
similar form, except that the intermediate division is the longest, and terminates in a point; 
on each side of this point two parallel, yellowish-white spots occur, the four forming a 
transverse row; a series of black and yellowish-white spots, disposed alternately, extends on 
each side of the medial line of the posterior half of the abdomen ; the first black spot of each 
series and the first yellowish-white one, which is much the longest, are the most conspicuous; 
sometimes the space between these series is obscurely marked with black and yellowish-white, 
curved, transverse lines; the sexual organs are of a reddish-brown colour, and have a lon°-i- 
tudinal septum in the middle. 
The male is smaller and darker coloured than the female. The cubital and radial joints 
of its palpi are short; the digital joint, which has a tinge of brown, is of an oblong-oval 
form; it is convex and hairy externally, and concave within, at the base; this concavity com¬ 
prises the palpal organs, which are neither highly developed nor very complicated in structure, 
and are of a dark, reddish-brown colour. 
M. Walckenaer, regarding this handsome spider as identical with Lycosa allodroma , has 
placed the name given to it by M. Hahn among the synonyma of that species (‘ Hist. Nat. 
des Insect. Apt.,’ tom. i, p. 330). Of the specific distinctness of Lycosa picta, however, no 
doubt can be entertained by those observers who have had an opportunity of inspecting adult
